PROBLEM TO BE SOLVED: To provide functionalized elastomer having a high rebound physical property (low hysteresis) to reduce the rolling resistance and to improve the tread wear characteristics of tires.SOLUTION: The present invention is directed to a functionalized elastomer having the formula (P-B)-X, where P is a polydiene segment, B is a styrenic monomer residue, n is the number of styrenic monomer residues, and Bis a polystyrenic segment; X is a multifunctional terminator residue, and q is the number of (P-B) chains coupled to X; where for q=1 the weight percent of the functionalized elastomer is at least 90 percent by weight.SELECTED DRAWING: None |
